Configuring Logging using Solr Cloud Operator

I am trying to configure logging but i cannot seem to get it to work. Is there an example somewhere I can reference?

1. Turn down the logLevel from INFO to WARN
2. Write the logs as JSON to the CONSOLE

My SolrCloud has these settings but both my Solr and Zookeeper (using the embedded ZK) are logging at INFO

```
spec:
replicas: 1
solrImage:
repository: solr
tag: "9.9.0"
solrLogLevel: WARN
```

This is pummeling our logs.

Start by tracing how the SolrCloud spec's solrLogLevel setting is handled for Solr and embedded Zookeeper, then check the operator's logging configuration documentation or examples. Done means WARN-level logs are applied to both components and JSON logs are written to the console without the current INFO-level volume.
